Electronic device and fan control method

Abstract

An electronic device including an audio module, a monitoring module and a fan is provided. The audio module generates an audio signal and an audio parameter according to audio data, and transmits the audio signal to a play device. Furthermore, the monitoring module determines a speed of fan rotation base on the type of the play device, the audio parameter and a sensed temperature. Then, a rotation speed of the fan is adjusted according to the determined speed of fan rotation.

AI Technical Summary

Benefits of technology

[0007]The invention is directed to an electronic device, in which one of a first temperature-controlled rotation speed table and a second temperature-controlled rotation speed table is selected to control a rotation speed of a fan according to a type of a play device and an audio parameter. In this way, when a sound sent by the electronic device overshadows a fan noise, the rotation speed of the fan is enhanced, so as to improve the operating performance of the electronic device.

[0008]The invention is directed to a fan control method, by which one of a first temperature-controlled rotation speed table and a second temperature-controlled rotation speed table is selected to control a rotation speed of a fan according to a type of a play device and an audio parameter, so as to improve the operating performance of the electronic device.

[0015]According to the above descriptions, in the invention, one of the first temperature-controlled rotation speed table and the second temperature-controlled rotation speed table is selected to control the rotation speed of the fan according to the type of the play device and the audio parameter. In this way, when the sound sent by the electronic device conceals the noise of the fan, the rotation speed of the fan is enhanced, so as to improve the operating performance of the electronic device.

Problems solved by technology

However, when the system temperature is not changed, the existing fan control method cannot control the fan rotation speed according to a variation of surrounding environment of the computer system.

For example, young people often spend a long time to play computer games, and noisy game music is output by a speaker during the game playing process.

However, according to the existing fan control method, the fan rotation speed is adjusted only when the system temperature of the computer system is increased to a threshold.
